Merge tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon fixes from Guenter Roeck:
- Fix a resource leak in tmp103 driver
- Add support for two more processors to fam15h_power driver
- Also fix a bug in the same driver to only report the power level on
chips which actually support reporting it
* tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging:
hwmon: (tmp103) Fix resource leak bug in tmp103 temperature sensor driver
hwmon: (fam15h_power) Add support for two more processors
hwmon: (fam15h_power) Make actual power reporting conditional
